Abstract

In cases when cellular phone 1a plays back a 96×80 pixel video while creating an E-mail with a video attachment or receiving an E-mail with a video attachment, the data communications device enlarges the video periphery and performs playback in 128×96 pixels. Even though the expansion method employed simply enlarges the video periphery, enlarges the scale factor ratio linearly from the center section extending to the periphery and enlarges the scale factor ratio exponentially from the video center section extending to the periphery, a reduction in video visibility by expansion is prevented as the center section is set to 1× (one fold). Consequently, in video playback the common problem of decreased visibility from image deterioration does not occur, resulting in the display area being utilized effectively with enhanced visual effects and image quality.

Claims

1-8. -8. (canceled)

9. An E-mail document display method with a video attachment comprising the steps of:

displaying video associated with an E-mail document at least on a display performed in a communications facility which performs data communications of said video by way of wireless signals;

reading out stored video In memory;

enlarging the video periphery; and

performing to said display video playback in a display practicable area size of said display.

10. The E-mail document display method with a video attachment according to claim 9, further comprising the steps of:

identifying expansion direction Information appended to said video attachment;

enlarging said video attachment periphery where the expansion direction information Is judged indicating expansion; and

performing to said display video playback in a display practicable area size of said display.

11. The E-mail document display method with a video attachment according to claim 9, wherein in cases when enlarging the video during playback is directed,

said enlarging step enlarges the video periphery, and

said performing step performs video playback in the display practicable area size of said display.

12. The E-mail document display method with a video attachment according to claim 9, wherein said E-mail document display method includes the steps of simply enlarging the video periphery and performing video playback.

13. The E-mail document display method with a video attachment according to claim 9, said E-mail document display method further includes the steps of enlarging the scale factor ratio linearly from the center section extending to the periphery and performing video playback.

14. The E-mail document display method with a video attachment according to claim 9, said E-mail document display method further includes the steps of enlarging the scale factor ratio exponentially from the center section extending to the periphery and performing video playback.
